How to correctly configure speakers and power amplifiers
How to Configure Speakers and Power Amplifiers Correctly Part 1: Impedance Matching
It means that the rated output impedance of the power amplifier should be consistent with the rated impedance of the speaker. If the rated impedance of the loudspeaker is greater than the rated output impedance of the power amplifier, the actual output power of the power amplifier will be less than the rated output power. If the rated impedance of the loudspeaker is less than the rated output impedance of the power amplifier, the sound system can work, but the power amplifier is in danger of overload, which requires the power amplifier to have perfect overcurrent protection measures to solve it, and the impedance matching requirements of the electron tube power amplifier are more stringent.
How to Configure Speaker and Amplifier Correctly Part II: Power Matching
When the rated power of the loudspeaker is inconsistent with the rated power of the power amplifier, the power of the power amplifier is only related to the impedance of the loudspeaker, but has nothing to do with the rated power of the loudspeaker. Whether the power of the speaker is the same as that of the power amplifier or not has no effect on the power amplifier, but only on the safety of the speaker itself.
How to Configure Sound Box and Power Amplifier Correctly Part III: Damping Coefficient Matching
The damping coefficient kd is defined as kd= the rated output impedance of the power amplifier (equal to the rated impedance of the speaker)/the output internal resistance of the power amplifier. Because the output internal resistance of the power amplifier has actually become the resistance device of the speaker, the kd value determines the resistance of the speaker.
